摘要

Ultracold plasmas(UCPs),created via photoionizing laser-cooling atoms in magneto-optical trap(MOT)[1],have the temperature of ions around 1 K and the temperature of electrons ranging from 1 to 1000 K.Due to the low temperature of the ions,the ultracold plasma is considered to be strongly coupled,in which the Coulomb effect dominants the evolution of plasmas.Here we present an idea and a test to measure the temperature of ions in UCPs[2]using a novel method of velocity map imaging(VMI).
